4.5 S4 OUTPUT RELAYS

4.5 S4 OUTPUT RELAYS
Five of the six output relays are always non-failsafe, R6 Service is always failsafe. As failsafe, R6 relay will be
energized normally and de-energize when called upon to operate. It will also de-energize when control power
to the 469 is lost and therefore, be in its operated state. All other relays, being non-failsafe, will be de-ener-
gized normally and energize when called upon to operate. Obviously, when control power is lost to the 469, the
output relays must be de-energized and therefore, they will be in their non-operated state. Shorting bars in the
drawout case ensure that when the 469 is drawn out, no trip or alarm occurs. The R6 Service output will how-
ever indicate that the 469 has been drawn out.

a) RESETTING THE 469
A latched trip or alarm may be reset at any time, providing that the condition that caused the trip or alarm is no
longer present. Unlatched trips and alarms will reset automatically once the condition is no longer present. If
any condition may be reset, the Reset Possible LED will be lit. All Block Start features reset automatically when
the lockout time has expired and the trip has been reset.
The other relays may be programmed to All Resets which allows reset from the front keypad or the remote
reset switch input or the communications port. Optionally, relays 1 through 6 may be programmed to reset by
the "Remote Reset Only" (by the remote reset switch input or the communications port) or "Keypad Reset Only" (reset
only by relay keypad).
NO trip or alarm element must EVER be assigned to two output relays where one is Remote
Reset Only and the other is Keypad Reset Only. The trip or alarm will be unresettable if this
occurs.
WARNING
b) EXAMPLE
Serious trips such as Short Circuit and Ground Fault may be assigned to R2 so that they may only be reset via.
the remote reset terminals (D18 and D23) or the communication port. The remote reset terminals should be
connected to a keyswitch so that only authorized personnel could reset such a critical trip.
• Assign only Short Circuit and Ground Fault to R2
• Program R2 AUXILIARY to "Remote Reset Only"
